To all whom it may concern.:

Be it known that I, HENaY K. SHANOK, a citizen of the United States. and a resident of Cleveland, .count of Cuyahoga," State of Ohio, have invente certain new land useful Improvements i A4lxplosivc Engines, of

a full, clear, and exact description, such as will enable others skilled in the art' to which it appertains to make and use the same.

My'invention relates to improvements in ex losive-engines in which some one of the vo atileproducts of hydrocarbon oil, as naph. tha or gasolene, is employed as motive power when commin led with the requisite proportion of air in t e cylinder.

The objects of the invention are, primarily, to obtain a more perfect admixture of the hydrocarbon gas and air before entering the cylinder, to insure a speedy and complete exhaustion thereof from the cylinder, and to provide a form, of spraying device for the m0- tive Huid and intermediate gas-and-air'reservoir or chamber by means of which it is more thoroughly condensed and commingled with the air and in condition for immediate use in l theVcylinder-a further object of great importance.

My invention further consists in the` combination and arrangement of parts and construction of details, as hereinafter described, shown in the accompanying drawings, and

In the accompan ing drawings, Figure 1 is a side elevation of tlie complete device, showing the various connections of the engine with the feeding .device,"fuelreservoir, airpressure'chamber, filter, pump, and safetyvalve, the pump, filter, and safety-valve being shown in vertical central section. Fig. 2 isa plan view of the same. Fig. 3 is an enlarged plan of the engine'alone.l Fig'. 4 is a vertica longitudinal'section lon center line of one of the engine-cylinders, showing inlet and commingling chambers also in section. F ig. y 5 is a transverse section through double cylinder, com ressing chambers, 'and partial longitudina section through the-inlet-chamber which bridges over the two compressionchambers of the engine. Fig. 6 is a longitudinal section 'of the spraying valve and tube tween the tw'o cylinders'. Fig. 7 is a longitudmal section of one of the cylinders, showing lector turns the pure gas toward the upBpe' the admission and exhaust openines uncovered by the piston and illustrating the action l ofthe deector in driving out the consumed Gas.

i: I n the figures, 1 1 are the cylinders of a twincylinder engine; 2, the piston of each engine;

3, the piston-rods, and 4 the cross-heads. v

Each cylinder is rovided witlr tight cylinder-heads 5 at eit er end and on the upper side with an inlet-port 6, arranged transversely through the shell to admit the commingled air and gas behind the piston.v @This is placed approximately in a central position between the cylinder-heads. At the front of, the cylinder and also on the upper side close to the cylinder-head is a second port 7,

through which the commingled air and gas to be compressed is drawn into the cylinder in front ofthe piston. The exhaustort is seen at 8 at the lower side of the cylin er and opposite to the admission-port, but in advance thereof, the forward edge of the exhaust-port being vertically underneath the rear edgefoi the admission-port above. The exhaust-port is large enough to give an easy exhaust and is so placed inorder to permit the exhaust to commence in advance of the admission on the forward stroke of the piston and to .continue during the admission, so that the spent gases may be thoroughly driven out by those freshly entering the cylinder, thus obtaining .a greater power of explosion, since the entire charge is pure, than could be obtained if vitiated rases were mingled with pure gas. To great y assist in this operation, the upwardly and rearwardly extending lip or flange 9 is secured to the back of the piston. This de- 1 rear extremity of thc cylinder, as seen in iv. 7,'whence it circles about the end of the cyliinder and quickly drives out the vitiated gas through the exhaust-port 8, thus filling the cylinder much more quickly -with pure gas and thoroughly cleansing it of the spent gas.

ln order to Obtain a thoroughly-commingled supply of air and gas to the cylinder and also to supply it under compression, the followingform of constructionis employed: 10 is thc reservoir in which the motive liuid is stored. 11 is the pipe leadingr therefrom to the filter 12, by means of which impurities in the oil are prevented from entering the pump or valve -and interfering with itsV action. 13 is the pump, by means of which a constant stream of' oil issupplied to the equalizingchamber 14, which is filled with air com f pressed as the oil enters the chamber, thuli maintaining a steady even degree of .pressure ICO sin-Lage thereon. is 'the spraying-tube,into which reduced at 28 and loosely passes through the I the oil is next in' turn received, and 16 is the valve at the outer end of this tube, by means yof which thestream of oil under pressure is 5 finely vaporized and in the form of mist is projected into the spraying-tube. In this tube openings 17 admit the air, which is drawn into thetuhe by the suction of the piston in the cylinder. There heingtwo cylinders, a

1o chamber 18 bridges them and receives the jet of commingled air, and gas and retains the mixture' until drawn into the final commingling and compressing chambers 9 and cylinders below. A safety-valve 35 returns the 5 oil, if the pressure becomes too great, to the reservoir 10. The construction and use of these chambers and. intermediate valves may f be described as follows: The cylinders being alike the description of one will serve for both. zo.As the piston travels backward it sucks down Athe mixture of gas and air from the bridgechamberthrough the vvalve 20, 'the tension upon which is controlled by means of the spring 21 encircling its stem 22. y B this 25 means the chamber. 19 is filledy with t e explosive mixture, which is further drawn into thev engine cylinderI through' the port 7. When at the end oftthe piston-stroke, the chamberv 18 and cylinder are both illrl with 5o, the mixture and the piston beginsfto move forward, the suction thereof ceases', and the valve 20 closes to stop the entrance of-rnore -of the gaseous mixture. The compressionof the gas in the chamber v19 then commences 3 5 andcontinues until the piston ceases its forward movement, the size of the chamber 19 being so proportioned in relation to the cylinder as to `receive and hold the requisite amount of the compressed explosive. at the re- 40 uired degree of density to serve as vone charge or the cylinder. In this manner each charge can be mathematically portioned out without waste or variation in density. It will readily be seen that since a short period of time must elapse during the process of cornpression in the cylinder and chamber and in the bridging-chamber before the valve opens to admit the mixture to the compressionchamber there will be given an opportunity 5o for the atoms of air and gas to combine and forrna homogeneous mixture of evenxgxuality throughbit which willbe in condition tor immediate use in the cylinder and will simulta- :.n'eou'sly explode through all its parts.

5 5- In asingle engine the bridge of course would be unnecessary, and only one valve would'be required and one end of the chamber only wouldbeneededr I A very im ortant feature of the invention 6o is found in tie construction of the vaporizing-tube, shown in Fig. 6. Here 25 is the valve-stem, slightly flattened on the sides, so as to aiord passage to the fluid, and conical at 26 to engage the conical seat 27. The

i inner extremity of the valve is cylindiicallyl the outer end 'of the tube opening 29 in the seat. This cylindrical stem compels the iet to take a longitudinal direction and prevents any cross-currents,such as are generally found in taper needle-valves when not well centered In order to project the finely-sprayed or inist-like fluid through the tube in parallel lines, so that it will be .mingled with and completely taken up by the air entering the openings 17, the admissionopening is made with parabolically-curved sides, as seen at 31. The effect of this is to proj ect the mist longitudinally of the tube as fast as it is atomized by the valve. In this manner the air and being propelled together through the tube intothe bri (ige-chainber amuch more intimate commingling thereof can be obtained than in any other way.

Having described my invention, what l. claim as new, and desire to secure by Letters Iatent, is'- 1. In a twin-c dinder explosive-engine, the combination with the cylinders having closed ends, of duplicate compression-chambers independently mounted thereon and of predeterminedless capacity than the cylinders therefor, each provided with a passage communicating with the front of its respective cylinder, an admission-port from each compression-chamber centrally placed in each cylinder between its ends, an exhaust-port for each cylinder arranged toex'h'aust in ad- Vance of the admission., a commingling-chamber arranged to bridge the compression-chambers, duplicate passages between the condensing-chambers and the bridge-chamber, automatic valves therein,.an elongated spraying-tube entering the bridge-chamber between the compression-chambers, a valve at air-inlets therefor, and a delivery-nozzle for the valve adapted to discharge vapor longitudinally of the tube, substantially as described. 4
